This document provides specifications for the HANS-C series of noise suppressor resistors developed for use in automotive ignition systems. The resistors are wire wound and come in resistance values from 1K0 to 10K with tolerances of 20%, 10%, or 5%. They are designed to reduce radio frequency interference caused by electrical discharges in engines. The document lists the mechanical specifications including dimensions and minimum inductance values as well as electrical specifications, performance requirements, and ordering information for the resistors.

The HANS-C series has been developed to be introduced in automotive ignition systems to reduce Radio Frequency Interference (RFI),
which are caused during electrical discharges on petrol engines in both cars and motorcycles. In order to meet the current legislation in
force to reduce these disturbances, the introduction of these Noise Suppressor resistors in the rotor of the distributor or the spark plug
leads can ensure compliance.
